ROOF-JOINT.

Specification of Letters Patent.

Patented Dec. 2, 1913.

A lication filed January 27, 1913. Serial No. 744,448.

To all whom it may concern:

Be it known that 1, CHARLES A. OvnR'roN, a citizen of the United States, residing at Coeur dAlene, in the county of Kootenai and State of Idaho, have invented certain new and useful Improvements in Roof- Joints, of which the following is a specification.

This invention relates to devices for forming a water-tight joint between a roof and a pipe passing therethrough, and its object is to provide a device of this kind which can be readily adjusted to fit pipes of different diameters, and which can be securely clamped around the pipe to make a strong, durable and tight joint.

The invention also has for its object to provide a joint which can be easily and quickly made.

These objects are attained by a novel conbination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which- Figure l is a side elevation showing the application of the invention. Fig. 2 is a perspective view of the parts constituting the joint before said parts are assembled. Fig. 3 is a horizontal section on the line 33 of Fig. 1.

As shown in the drawing, the device comprises a frusto-conical sheet-metal sleeve 5 to the lower edge or base of which is secured an outstanding flange 6 whereby the sleeve is secured to the roof in any suitable manner. The base of the sleeve is cut slanting, which places the flange at a corresponding angle so that the device may be applied to a sloping roof. For fiatroofs, the sleeve will be arranged perpendicular to the base flange. The diameter of the sleeve is such that the soil or other pipe 7 may pass therethrough.

The sleeve 5 has an integral outstanding crease 8 extending throughout its entire length, from the top to the base. The crease is V-shaped in cross-section and gradually decreases in depth from the top to the base of the sleeve, at which latter portion of the sleeve the apex of the crease merges with the outer surface of the sleeve.

The purpose of the afore-mentioned crease 8 is to enable the sleeve 5 to be contracted or drawn tight around the ipe 7, in order to make a water-tight joint. This can be readily done by pinching the opposite walls 'of the crease together. It will therefore be seen that the sleeve is adapted for pipes of different diameters within certain limits.

The top of the crease 8 is cut away at an acute angle to the top edge of the sleeve 5 and over said top of the crease is placed a cap 9 which closes up the space between the opposite walls of the crease. This cap has depending side flanges 1O fitting over the outside of the walls of the crease. That edge of the cap which is next to the pipe 7 is-curved to fit the latter. The flanges 10 and the contiguous portions of the walls of the crease have alined perforations to receive a bolt 11 which is secured by a nut 12 whereby the cap is fastened in place on the crease. This fastening may also be employed for drawing the walls of the crease together to tighten the sleeve around the pipe as hereinbefore described. When the cap is in place the top of the crease is covcred whereby snow and rain is kept out of the same. The cap does not interfere with the adjustment of the sleeve around the pipe.

It will be understood that only the top edge of the sleeve is clamped around the pipe, the diameter of the remainder of the sleeve being such that the pipe is spaced therefrom, in view of which the necessary adjustment to suit the pitch of the roof may be made.

The device herein described is simple in construction, it can be easily and quickly applied, and it makes a strong, durable and thoroughly water-tight joint.

I claim:

1. A roof joint comprising a sleeve adapted to encircle a pipe, said sleeve having an outstanding longitudinal crease, the side walls of which crease converge from the body of the sleeve and have their outer ends integrally united, and means for drawing said side walls of the crease together to contract the sleeve.

2. A roof joint comprising a sleeve adapted to encircle a pipe, said sleeve having an outstanding crease extending down from the top thereof and adapted to be drawn to gether to contract the sleeve, and a cap separate from the sleeve and the crease thereof, said cap fitting over the top edge of the crease.

3. A roof joint comprising a sleeve adapted to encircle a pipe, said sleeve having an outstanding crease extending down from the top thereof and adapted to be drawn together to contract the sleeve, a cap closing the space between the Walls of the crease at the top thereof, said cap being separate from the sleeve and the crease, and having depending flanges fitting the sic le Walls of the crease externally and the top of the cap having its inner edge curved t0 fit the outer surface of the pipe, and fastening means[ passing through the flanges of the cap and the side Walls of the crease.

In testimony whereof I aflix my "signature in presence of two Witnesses.
